Steve Loughran created YARN-1042:
------------------------------------
Summary: add ability to specify affinity/anti-affinity in
container requests
Key: YARN-1042
URL: https://issues.apache.org/jira/browse/YARN-1042
Project: Hadoop YARN
Issue Type: New Feature
Components: resourcemanager
Affects Versions: 3.0.0
Reporter: Steve Loughran
container requests to the AM should be able to request anti-affinity to ensure
that things like Region Servers don't come up on the same failure zones.
Similarly, you may be able to want to specify affinity to same host or rack
without specifying which specific host/rack. Example: bringing up a small
giraph cluster in a large YARN cluster would benefit from having the processes
in the same rack purely for bandwidth reasons.
